BRUSH.

Application filed January 13, 1927. Serial No. 160,882.

The present invention relates to improvements. in brushes, and more particularly to brushes of the type having cylindrical heads, constructed for rotation and especially for greasing pans in bakeries.

Brushes of the type mentioned usnally comprise a head composed of a cylindrical backing provided with holes orsockets, int-o which'tufts or bunches of brush material are secured. The head is mounted upon a hollow brush spindle, through which grease is supplied to the brush. Usually a plurality of these heads are mounted upon'a n achine, so asto accelerate the greasing operation.

Serious difficulties have been experiencedwith these brushes, as constructed heretofore. @ne of these difficulties consists in that the grease is apt to flow down the cylindrical fa'ce of the brush past the brush material, instead of being taken up in its entirety by the brush material and applied to the pan, thereby resulting in waste of grease. Another difficulty consists in that these brushes, as constructed heretofore, are

exceedingly hard to clean, the result being that the grease left therein becomes rancid and spoils the new charge of grease when the operations are resumed.

The main object of the present invention is to so construct the brush that the difliculties above referred to are overcome.

Another object of the invention is to so construct a brush of the type mentioned which is simple in construction, efficient in operation, durable in use, and capable of manufacture on a commercial scale, or in other words one which is not so dificult to manufacture as to be beyond the reasonable cost of such a contrivance.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention. is illustrated in the accompanying drawings, in which i i Figure 1 is a central vertical section taken through a brush constructed in accordance with the present invention; andrFigi 2 'is a bottom plan View thereof.

Broadly speaking, the improved brush consists of a hollow cylindrical metallic backing, having a cylindrical body inserted therein for connection with a rotatable spindle. The cylindrical backing is pm vided upon its outer surface with peripheral grooves 'or corrugations, which prevent the grease from flowing past the tufts "or bunches of brush material, the said tufts. 0i bunches being secured in sockets whichextend from the. said grooves or corrugations through the'cylindrical backing; Re e r ng ow t e d a gs th nameral "110 indicates theba'cking of the improved brush, said backing being in the form of a hollow cylinder, preferably made of metal. In the outer cylindrical face of this element are formed deep peripheral grooves or corrugations 11, all extending in parallel relation to each other at right angles to the longitudinal axis of the said cylinder. In one face of the peripheral grooves of the backing are formed sockets or holes 12, each extending through the backing at an acute angle to the longitudinal axis thereof and serving to receive a tuft or bunch of brush material 13. These tufts or bunches are, preferably, folded or doubled and are drawn into the sockets or holes by a wire 14, engaging the fold of the tuft or bunch, thereby securing the latter to the backing. At the top and bottom of the cylinder are provided, in the bore thereof, inwardly extending annular shoulders 15 and 16, respectively, to which are closely fitted the flanges 17 and 18, respectively, of a cylindrical body 19, which is disposed in the hollow cylinder 10 and held in place by screws 20, or otherwise. The screws 20 are threaded intothe cylinder 10 and cylindrical body 19, as clearly shown in the drawings. The cylindrical body 19 is provided centrally with a bore 21, extending longitudinally through the same. Through the cylindrical body 19 is driven a horizontally extending pin 22, seated in longitudinal slots 23 in a hollow spindle 24, the latter being partly disposed in the bore 21.

In use, rotating motion is im arted to the spindle 24, whereby the bran is rotated.

Grease is supplied to the brush through the hollow spindle, the grease being applied to the baking pan, brought into contact with the brush material. The brush is held in vertical position as shown in the drawings, so that the grease, which has a tendency to flow down the outer surface of the cylindrical backing, can be arrested by the deep peripheral grooves or corrugations above referred to. Little or no material at all is thus wasted. It is to be noted that, for cleaning purposes, the brush can be conveniently removed from the spindle 24c, and the cylinder 10 and cylindrical body l9 taken apart. The last-named two elements can thus be easily cleaned on their outer and inner surfaces.

What I claim is: v 1. A brush comprising a hollow cylindrical backing provided in its outer cylindrical surface with deep peripheral grooves extending in parallel relation to each other and at right angles to the longitudinal axis of said backing, said backing being provided with sockets extending from said grooves at an acute angle to the longitudinal axis of said backing, tufts of brush material secured in said sockets, abody fitted into said backing and secured thereto, said body being provided with a central bore, a pin extending transversely through said bore, and a rotatable hollow spindle fitted into said bore provided with longitudinal slots in which said pin is seated.

2. A brush comprising a hollow cylindrical backing provided in its outer cylindrical surface with deep peripheral grooves extending in parallel relation to each other and at right angles to the longitudinal axis of said backing, said backing being provided with sockets extending from said grooves at an acute angle to the longitudinal axis of said backing, tufts of brush material secured in said sockets, annular shoulders projecting inwardly from the inner surface of said backing at the top and bottom of said backing, a cylindrical body'in said backing provided with flanges fitting snugly said shoulders, means for fastening together said backing and cylindrical body, said cylindrical body being provided with a central-bore, a pin extending transversely through said bore, andia rotatable hollow spindle fitted into said bore provided with longitudinal slots in which said pin is seated.
